GENERAL DESCRIPTION
The ADP122/ADP123 are low quiescent current, low dropout
linear regulators. They are designed to operate from an input
voltage between 2.3 V and 5.5 V and to provide up to 300 mA of
output current. The low 85 mV dropout voltage at a 300 mA load
improves efficiency and allows operation over a wide input
voltage range.
The low 170 μA of quiescent current at full load makes the ADP122
ideal for battery-operated portable equipment.
The ADP122 is capable of 31 fixed output voltages from 1.75 V
to 3.3 V. The ADP123 is the adjustable version of the device and
allows the output voltage to be set between 0.8 V and 5.0 V by
an external voltage divider.
The ADP122/ADP123 are specifically designed for stable operation
with tiny 1 μF ceramic input and output capacitors to meet the
requirements of high performance, space constrained applications.
The ADP122/ADP123 have an internal soft start that gives a
constant start-up time of 350 μs. Short-circuit protection and
thermal overload protection circuits prevent damage in adverse
conditions. The ADP122/ADP123 are available in a tiny, 5-lead
TSOT package for the smallest footprint solution to meet a
variety of portable applications.
